I placed an order to buy a couple hundred shares in a company at the cost of 165. I clicked continue. It then took me to another page and gave me 15 seconds to complete at that same price.
I clicked OK and my order was executed. I immediately looked at my position and it said that I was down roughly 10%. It appears that the cost per share had gone to 187 although it still says on a separate page that the executed price was 165. At no point from when the stock market opened did share price rise above 168, yet I'm down money straight away and I'm not sure why or what I have done wrong.
